COWL-VENTILATOH MOUNTING FOR FLEXIBLE BODIES.

Application filed July 533,

111 that type of sound-deadened closed bodies :lor automobileswherein the body composed o'l. a skeleton frame the elements of which are so connected that the skeleton may weave and yield to the distortions f the supporting chassis frame and (his skeleton is covered by a l'lQfllJlQ covering oi? nonrcsonant fabric or other similar ma rial,

The object or' my present invention to provide a cowl ventilating means oil such character as to be capable oi? incorp-zuraliioa "with such a flexible body sliruclure.

The accompanying drawings illiiistrarc my invention.

Fig. 1 is a plan of the from; end oi: automobile the body, of which is a flexible skeleton fabric covered structure in the cowl o'l? which my improvement has been incorporated Fig. 2 is a perspective oi lhe flexible skel ion cowl with my iu'iproved veni ilalor in place, the fabric covering being omil'led;

Fig. 3 is a plan of the vol i ilai ing frame and forward support lherc'fo Fig. i a longitudinal secl'ion oi 3 and a Fig. 5 a plan of a modified form oi? rentilator supporting frame.

In the drawings and ll iudicalie the front and rear bars of a flexible cowl shalelon, said parts being flexibly aesoi'ialcd with their frame members 13 in such manner that rhoy do not directly abut each other but have their adjacent portionsslightly separated and connected by light flexible metal connected members 14, the construction being such that the sacleron frame may weave or yield to the distortions of ihe si'ippm'ting chaesis frame. It has been found :ulvisablo in cowl constructions of this kind lo provide upper corner elenlcntslo of thin metal plate secured to elements of the flexible cowl frame, along two edges only, an indicated at '16 and 17, 1 1c :l'ront edges, generally, oi the plaice 15 being slidably SUPPOl'l'lkl in 1mmlS in the upper corners of lhe lron't bar My ventilal'or support compi a hori mental frame upon which conveniently a metal frame 9,1 of am'ular cross section over which a ventilator" cover 22 may lit in a Well known manner. The frame 20 is provided, most conveniently at its rear edge, with extensions 23, which are projected into mortises 24; in the rear bar 11 and secured by fastening screws 25.

on the scale ible cove iuo unto:

was, Serial No. 294,8'52.

All the opposite side frame 20 is provided with a 'l'onguc 2-6 adapted to lie in a notch 227 in the upper sau'lacc o'l' :lronl' bar 10 and held against vertical displacement by a bar 28 the upper surface of which is preferably flash with the upper surface of front bar 10 the arrangement being such that a covering fabric 30 (Fig. 1) may be stretched over the cowl frame and secured along its edges to rho flexibly connected cowl l'ranic elements ll), 11 and This fabric covering will be provided with an opening appropriate to the opening through the frame 21 and, around the edges of are opening will be secured to the ventilator supporting frame 20. i

It will be noted that the supporting frame 20 is so associated with the front and rear bars 10 and ii that llmse bars may weave relal'ive "("0 each other, the flexibility of the covering 30 permitting this weaving without ruplure of the cover.

W hilc I believe that a three point support for the cowl supporting frame 20, as shown in 2 to al, is preferable, it will be readilv understood that modifications may be made without departing from my invention, as for instance, as shown in Fig. 5 where The ventilator supporting frame 20' provided with two extensions 26 each ol which lies in a notch 27 in the aasocialcd frame elcinculll) and is held against vertical dis- PlfiCQlllUllh by bridge bar 28.

I claim as my invention: i

The combination will flexibly connected wwl-sliclclion elcmcnls of an automobile one overlapping itissoeialiion of ventilator" support and cowl ckclclon bcing slidably in one plane, and means :for prex cnting separon oil said overlapping association at r l: an to the sliding plane, and a flcxing connected to said cowl skeleton elenlcnls and the ventiarlor support.

In witness whereof, I, B, ll lonmrrn l.wmran have hereunto set my hand at lndianap is, Inilmna, this 20th day of July, A, 1). onclilumsund ninehundred and twenty-eight.
